Question

Given f(x)=5x−3 , find f(5).
A. 17
B. 22
C. 12
D. 20

Answer 1

To find f(5), simply substitute 5 for x in the function f(x) = 5x - 3 and perform the arithmetic to get 22, which is option B.

Step-by-step explanation:

To find f(5) for the function f(x) = 5x - 3, we substitute 5 for x in the function:

f(5) = 5(5) - 3

Next, we perform the multiplication:

f(5) = 25 - 3

Finally, we subtract 3 from 25:

f(5) = 22

The correct answer is B. 22.
